Here’s the reality: in the U.S., people over 60 now make up more than a fifth of the population, and by 2034, older adults are expected to outnumber children (United States Census Bureau). This demographic shift means more people face climate risks, emphasizing the importance of tackling these hazards seriously.
Why Seniors Are More Vulnerable
Aging changes the way our bodies respond to environmental stress. Older adults often have health conditions like diabetes, heart disease, or respiratory issues that make it harder to cope with heat and air pollution. Considering these climate change risks for our senior population, medications, compromised immune systems, and limited mobility can further increase risks. In other words, what might just be a hot day for younger people can be life-threatening for someone older.
Living alone or relying on caretakers for daily tasks also adds layers of vulnerability. When extreme weather hits, whether it’s a heat wave or wildfire smoke, the challenge of getting help is compounded.
Key Health Risks of Climate Change for Older Adults
-
Heat-Related Illnesses
Older adults account for the majority of heat-related hospitalizations. Even slight temperature spikes can lead to dehydration, heat exhaustion, or heat stroke. If you live in a city, the urban heat island effect, where concrete and asphalt trap heat, can make the risk even worse, highlighting the climate change risks specifically for older adults.
-
Respiratory Problems
Wildfires and poor air quality can make breathing difficult. Smoke contains tiny particles and pollutants that can worsen asthma, COPD, or heart conditions. Even the pollen season is getting longer and more intense due to warmer temperatures and rising CO₂, which can trigger allergies or asthma attacks, becoming significant climate change risks for older individuals.
-
Insect- and Tick-Borne Diseases
Warmer temperatures also mean more mosquitoes and ticks. Older adults are more likely to suffer severe illness from diseases like West Nile virus or Lyme disease, adding to the climate change risks that need addressing.
-
Mental Health Strain
Extreme weather can be stressful. Feeling unsafe during a heatwave or wildfire, or being stuck indoors due to poor air quality, can increase isolation and anxiety. For those with cognitive impairments, the stress, especially from climate change risks, can be even harder to manage.
-
Water-Related Illnesses
Flooding and changes in water temperature can introduce bacteria or harmful algal blooms into drinking and recreational water. Older adults with compromised immune systems are particularly at risk for severe illness from contaminated water.
What You Can Do
- Stay cool and hydrated. Drink plenty of water, wear loose clothing, and stay in air-conditioned spaces. Don’t have AC? Reach out to friends, family, or local cooling centers.
- Monitor air quality. Check sites like AirNow to decide when it’s safe to enjoy outdoor activities without exposure to climate change-related pollution.
- Prevent bites. Use insect repellents and remove standing water where mosquitoes can breed.
- Make a plan. Keep an emergency kit with medications, food, water, and medical records. Establish a support network for backup if disaster strikes.
- Check in regularly. Reach out to elderly neighbors or family members, especially if they live alone or have health conditions. Make sure they know their emergency plan.
- Know your local resources. Many communities provide transportation, shelter, and assistance for older adults during extreme weather events.
Bottom Line of climate change risks for older adults
Climate change isn’t just an abstract concept, it’s affecting daily life, and older adults are at the frontlines. By staying informed about the specific climate change risks faced by the elderly, and being prepared and connected, we can help seniors weather extreme heat, poor air quality, and other climate-related hazards safely.
